There are tens of thousands of apps out there and from our own experience we know how hard it is to pick the best: most educational, tremendously engaging, greatly designed and easy to use apps.

We are parents ourselves and our kids have been 'using' various iPhone-like devices since they were as young as 8 months old.

We tried to use friends' recommendations, recommendation sites, app catalogs, blogs, recommendations published in app stores... It was difficult. As our kids grew, we had to repeat this search every few months, to catch up with the latest and greatest applications for the next age level.

We thought: what if someone could answer this question: my son/daughter is 3 years old, what 5, 10 or 20 apps should I buy to make the best use of my iPhone, iPad or Android device for education and play?
